[flake8-bugbear] Mark range as immutable (B008) (#27247)

Summary
--

Fixes #27245.

Test Plan
--

Updated existing snapshots. These were previously emitting both B006 on
the outer comprehensions and
B008 on the inner `range` call, but now the inner diagnostic is omitted
because `range` is
immutable.
